What reviewers say
Reviewers like the bright screen, comfortable design, useful running insights and generally reliable GPS and heart-rate tracking. They both flag limited smart features. Tom's Guide finds elevation data unreliable without an altimeter and gets six days with the display always on; TechRadar finds strong tracking despite older sensors but notes slower heart-rate response during intervals and faster GPS battery drain than claimed.
